Tilt Text for Roulette Wheel
So as your numbers are flat you should rather use an image texture than 3D meshes:


Give colors to the different parts of your mesh (here red, black, and whatever for the rest).





Unwrap the whole mesh.





In the UV Editor, export the UV layout.





Use this UV layout as a blueprint to create the numbers layout in an image editor. Keep a layer of white letters on a transparent background, save as PNG.





Import the image in Blender's UV Editor, align the UV correctly.





Go in the Shader Editor, select the red material, create an Image Texture node, plug it into a Diffuse, plug its Alpha into the Factor of a Mix Shader, plug the red Diffuse into the other socket of this mix. Do the same thing for the black material.





The numbers should appear on the roulette.
